ENVIRONMENTAL PROTECTION AGENCY
[FRL-5895-4]
EPA's Final Decision To Withdraw Phase I Total Maximum Daily
Loads (TMDLs) for Copper in certain New Jersey Waters of New York-New
Jersey Harbor
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: EPA has determined that certain New Jersey waters of the New
York-New Jersey Harbor are not water quality-limited for copper, and
therefore, Phase I copper TMDLs are not required for these water
segments. The New Jersey Harbor waters for which Phase I Copper TMDLS
are being withdrawn are defined as Newark Bay, Hackensack River below
the Oradell Dam, Passaic River below the Dundee Dam, Raritan River
below the Fieldsville Dam, and Raritan Bay. EPA is hereby issuing
public notice of its final decision to withdraw the Phase I TMDLs for
copper established by EPA on January 24, 1996.
DATES: September 19, 1997.
ADDRESSES: Copies of the responsiveness summary and relevant supporting
documents may be obtained by writing to Mr. Steven Wood, Fate & Effects
Team, U.S. Environmental

record may be made by contacting Mr. Steven Wood.

SUPPLEMENTARY INFORMATION:
I. Background
II. Public Notice of Draft Decision
III. Final Determination
I. Background
A TMDL, or total maximum daily load, is the maximum amount of the
pollutant that a waterbody can assimilate and still meet ambient water
quality standards. TMDLs are established for water quality-limited
segments, which are defined as ``any segment where it is known that
water quality does not meet applicable water quality standards, and/or
is not expected to meet applicable water quality standards, even after
the application of technology-based effluent limitations * * *'' (40
CFR 130.2(i)).
On January 24, 1996, EPA established certain phased TMDLs,
including waste load allocations (WLAs) and load allocations (LAs) for
copper. (61 FR 1930). Phased TMDLs were developed for copper because of
the limited ambient data and uncertainty in the model calibration for
the New Jersey Harbor waters. The Phase I TMDLs established in January
1996 required additional data collection in the New Jersey Harbor
waters before the establishment, as necessary, of revised Phase II
TMDLs. Phase II TMDLs were to be established only if the additional
data and/or modeling indicated that it was necessary to reduce point
and/or nonpoint sources of copper below Phase I levels. The New Jersey
Harbor waters affected by this action are Newark Bay, Hackensack River
below the Oradell Dam, Passaic River below the Dundee Dam, Raritan
River below the Fieldville Dam and Raritan Bay.
The New Jersey Harbor Dischargers Group (NJHDG), in cooperation
with the State of New Jersey and EPA, agreed to undertake the required
additional monitoring and modeling. The first phase of the monitoring
was designed to enhance the existing ambient database and to confirm
whether copper exceeded or potentially exceeded applicable water
quality standards in the above defined New Jersey Harbor waters. Based
on the results of this data collection effort, it was determined that
copper does not exceed the appropriate water quality criteria, and
therefore the Phase I copper TMDLs are being withdrawn, for the waters
mentioned above.
For the Arthur Kill and Kill Van Kull, the Phase I copper TMDLs are
not being withdrawn by today's action. The copper TMDLs for these
waters remain in effect. Additional monitoring and modeling is
currently ongoing for these two waters, and EPA expects to review these
data and take appropriate action. Such action may include, without
limitation, withdrawing the Phase I copper TMDLs, establishing Phase II
copper TMDLs or taking no action to revise the Phase I copper TMDLs. In
order to clarify EPA's position in this matter, EPA will, following
review of the data, publish notice in the Federal Register of the
results of its review and what further action, if any, it intends to
take on the Arthur Kill and Kill Van Kull copper TMDLs.
II. Public Notice of Draft Decision
EPA's proposed withdrawal was public noticed in the Federal
Register dated January 10, 1997 (62 FR 1454). A 30-day comment period
followed, during which EPA received five comment letters. All comments
have been addressed in a responsiveness summary which may be obtained
by writing or calling Mr. Steven Wood as referenced above.
III. Final Decision
EPA is noticing its final decision to withdraw the Phase I copper
TMDLs from the following New Jersey Harbor waters:
--Hackensack River below the Oradell Dam,
--Passaic River below the Dundee Dam,
--Raritan River below the Fieldville Dam,
--Newark Bay, and
--Raritan Bay.
This action has no effect on the TMDLs for other pollutants
established for these waters.
Dated: August 28, 1997.

Acting Regional Administrator.
